Abstract
The spatial-temporaldistribution of the dragonfly Coenagrion armatum on the lake Fadiha (Barabinskaya forest-steppe) with border type of overgrowing was studied. It was shown that the local population of this species is divided into two topical groups. In one group dragonflies develop in the water area and do not migrate to the shore after metamorphosis. In the other group dragonflies develop in the reeds and migrate to the shore for additional feeding after metamorphosis.
